Holy Mountain Sin Nanna Anniversary Bourbon Barrel-Aged Imperial Stout

Technical Details

Tasting Profile

Sin Nanna is Holy Mountain’s anniversary Imperial Stout, a decadent expression of their patient barrel program. Extended time in Kentucky bourbon barrels imparts deep notes of vanilla, oak, and warming bourbon spirit, layered over a base of roasted malt, dark chocolate, and rich caramel. Dark fruit emerges mid-palate alongside whispers of tobacco and leather, while the finish turns smooth and contemplative, with lingering oak tannin and gentle warmth. Anniversary double-barrel editions push the intensity further, delivering an opulent, full-bodied stout that rewards slow sipping and shows the brewery’s uncompromising mastery of mixed-culture and barrel-aged beer.

Food Pairing

Pair with a dense flourless chocolate torte or chocolate-bourbon pecan pie, where the dessert’s richness mirrors the stout’s roasted depth and vanilla-bourbon sweetness. Alternatively, serve alongside aged hard cheeses such as a sharp clothbound cheddar or smoky gouda, whose savory complexity and salt complement the beer’s oak, caramel, and tobacco notes beautifully.
